My desktop computer often loads Web pages much slower than my MacBook Pro, both through the same WiFi network.
I measured (for 2.4GHZ network with WiFi Analyzer) the signal drops from -30dBm to -60dBm when I move from WiFi router to where my desktop compter is located.
This is probably because:
- the computer is on the floor under the desk
- with WiFi antenna on the back directed to a metal radiator
- the WiFi router is in another room.
- a lot of my neighbours are using 2.4GHZ WiFi networks, probably leading to noise.
I cannot move the desktop onto the desk.
Which of the following solutions would resolve the problem:
- Replacing the WiFi card antenna with with a better and on a cable, so it can be placed above the desk?
- Replacing the current 2.4GHz WiFi card (Asus PCE N10) with 5GHz one? My WiFi router (Compel CH7465LG-LC, supporting 802.11ac) offers both 2.4GHz and 5GHz networks.
I also did tests with InSSIDer and it reported "Low Signal Strength" which confirmed my previous findings. It also warned with "Access Points Support Legacy Data Rates", but I don't think it is root cause of my problem my case, as I don't have many devices in my network to impact my PC. InSSIDer has also reported no problems with WiFi channel: my WiFi router is selecting channels automatically, currently 11, and WiFi adapter listens on the same. There doesn't seem to be any big channel overlap with other networks here:
